Representation of Integers on a Number Line
A number line is a straight
line representing negative and positive numbers. In number line the numbers are
placed at regular intervals and numbers to the right are greater than the
numbers to the left. Again the numbers on the left are smaller than the numbers
on the right. It is very helpful and easier to determine which numbers are
bigger and smaller by seeing on a number line. In a number line the positive
numbers are represented on the right side of zero and negative numbers are
represented on the left side of zero.
It can be concluded that the numbers on a number line are arranged in ascending order (that is smaller to bigger) when considered from left to right.
Now here are few examples showing the representation of integers on a number line.
1. Represent + 3 on a number line
Each place on the number line is marked as 1 unit. As, we know that numbers on the right of zero are positive and to the left are negative. Hence +3 on the number line will fall on the right side of zero and we have to jump 3 places to reach +3
2. Represent -2 on the number line.
Each place on the number line is marked as 1 unit. As, we know that numbers on the right of zero are positive and to the left are negative. Hence -2 on the number line will fall on the left side of zero and we have to jump 2 places to reach -2.
3. Represent +6 on a number line.
Each place on the number line is marked as 1 unit. As, we know that numbers on the right of zero are positive and to the left are negative. Hence +6 on the number line will fall on the right side of zero and we have to jump 6 places to reach +6
4. Represent -8 on a number line.
Each place on the number line is marked as 1 unit. As, we know that numbers on the right of zero are positive and to the left are negative. Hence -8 on the number line will fall on the left side of zero and we have to jump 8 places to reach -8
Therefore, this is how we can represent negative and positive integers on a number line.
